z l7 l9 HANGER is supported in such manner that a pressure component, due

to the load, is applied to the pressure-sensitive tape in a direction to oppose the force and/or moment which otherwise tends to pull the tape from the mount surface, thereby increasing the load-supporting capacity of the hanger.

SUMMARY OF THE INVENTION A mounting plate carries an arcuate member and is attachable to a surface by adhesive means such as a pressure-sensitive tape. The load is carried by a hook member which engages the.

central portion of the arcuate member, said hook member being mounted for movement relative to the arcuate member in response to the load weight. The, hook member applies a pressure normal to the arcuate member and the arcuate member transmits this pressure to end portions .of the mounting plate.

' An object of this invention is the provision of an improved hanger of the type which is affixed to a surface by means such as a pressure-sensitive tape.

An object of this invention is the provision of.a hanger having a mounting plate carrying an arcuate member and aloadcarrying member, said load-carrying member being movable with respect to the arcuate member in response to the weight of the load.

An object of this invention is the provision of a hanger comprising a mounting plate having an arcuate member extending from the front surface thereof, a load-supporting memberengaging the central portion of the arcuate member, means mounting the load-supporting member for movement relative to the arcuate member in response to the load weight, and a pressure-sensitive tape carried by the rear surface of the mounting plate.

The above-stated and other objects and advantages of the invention will become apparent from the following description when taken with the accompanying drawings. It .will be understood however that the drawings are for purposes of illustration and are not to be construed as defining the scope or limits of the invention, reference being had for the latter purpose to the claims appended hereto.

DESCRIPTION OF PREFERREDEMBODIMENT Referring now to FIGS. 1-3, a metal backing plate 10, is provided with two pairs of integral upstanding cars 11 and 12, each pair of ear having aligned holes formed therein for receiving the associated hinge pins 13 and 14. An arcuate member 15, has end portions curled about the supporting hinge pins 13 and l4, the median plane of the arcuate member being identified by the numeral 16. A hook member 17, constituting the load-carrying member of the hangar, passes through .a rectangular opening- 18 formed in the arcuate member and has its inner end portion curled around a hinge pin 19.:This hinge pin passes through aligned holes formed in a third pair of aligned, upstanding ears, one such ear being visible in FIG. 2 and identified by the numeral 20. These ears are spaced apart a distance somewhat greater than the width of the arcuate member and the hinge pin l9is displaced from the median plane of the arcuate member. Normally, the distance H is slightly greater than the radius r so that when the hook member is anchored to the hinge pin 19, the'outer surface of the hook member abuts against the upper wall defining the slot 18 and the comer 22 of the hook member depresses, slightly, the arcuate-member 15. This preloads the arcuate member and prevents the hook member from rotating in a counterclockwise direction aboutits hinge pin.

The rear surface of the mounting plate 10 carries a pressure-sensitive tape 23, whereby the hanger can be affixed to a wall or other surface. The arcuate member obeys the static and dynamic rule of arches. When a load, such as a picture; curtain rod, or etc., is carried, by the hook memberfas in-v dicated by the reference letter W in FIG. 2, the hook member. will pivot about its hinge pin 19 along the radius. r, which; radius is substantially less than the radius R of the arcuate member, thereby exerting an increased pressure against thearcuate member. The greater the load, the greater will be the pivotal movement of the hook member and, consequently, the

greater will be the pressure exerted against the arcuate" member. The arcuate member, in turn, transmits the pressure to the mounting plate, through the hinge pins l3.and l4, and this pressure is applied to the adhesive tape, whereby an increased counteracting force is required to pull the tape away from the surface. Consequently, the load-bearing capacity of the hanger is increased. The maximum load which can be supported by the hanger is limited by the structural characteristics of the hook member, arcuate member and mounting plate. These members can have an appropriate thickness, whereby the hanger is capable of supporting loads considerably heavier than those which can be supported by conventional hangers designed to be afiixed to awall by means of pressure-sensitive tape.

A modification of the hanger construction is shown in the cross-sectional view of FIG. 4. Here, the arcuate member 26 is formed integrally with the mounting plate 25 to which the pressure-sensitive tape 23 is attached. The pivotally supported hook member 27 passes through an opening formed in the arcuate member andhas an outer edge pressing against the central portion of the arcuate member.

Referring to FIGS. 5-7, there is shown another modification of the hanger construction. Here, the lower end of the arcuate member 28 is hinge-connected to the mounting plate 29 by means of the hinge pin 30. The upper portion of the mounting plate has an inverted U-shaped configuration terminating in a short leg 31. Disposed between the arcuate member 28 portion and the leg 31 is a generally V-shaped metal clip 32. The

convenience. However, it will be apparent that the hanger can be furnished without the pressure-sensitive tape, in which case the hanger can be affixed to a surface by means of a suitable adhesive. Since the load is supported at a point spaced from the surface to which the hanger is affixed, the resulting moment arm causes the upper portion of the hanger to be pulled away from the surface when the load exceeds a given weight. In hanger made in accordance with this invention, the pivotal movement of the hook member, in response to the load weight, develops a pressure component normal to and against the center of the arcuate member. The arcuate member transmits a portion of such pressure component to the mounting plate in a direction opposed to force which nonnally tends to pull the hanger away from the mount surface. This pressure component increases in correspondence with the increase in the weight of the load. Consequently, hangers made as herein described will support a load substantially greater than that which can be supported by hangers as heretofore made and having the same area affixed to the wall.

In the drawings, the mounting plate of the hanger is shown as a flat member but it will be apparent tat the mounting plate may have any shape corresponding to the surface to which the hanger is to be attached.
